Perhaps she hides because she knows you will be displeased with her, do you punish at all for the wetting ?
Thanks for your prompt reply. Also I would like to bring to your kind attention that when wets her pants/underwear she tries to hide. Rest in other activities she is very good in that. Sometime she tries to serve food for all the family members. But sometimes when we try to take her to toilet or change her wet
pants/underwear she screams. Dont know why?
Waiting for your valuable replies.
She is pretty young to be fully potty trained, and kids can regress from their training if there are traumas or changes in the house. Does she have a new baby brother or sister?
I would tend to play down the power struggles and just put her into pullups for another six months rather than make it into a huge drama.
My first instinct is that she may be doing it to get attention. If so, ignore it. If she can change herself, direct her to do so. Do not scold her or give her any feedback. When she tells you she has peed her pants, tell her "Okay, go change." Have her rinse and wring out her wet underwear and pants.
When she does use the potty, praise her loud and long. Focus on the behavior you want...ignore the other as completely as possible.
Do this for a few weeks consistently and see if you don't see a difference (it will take 2-3 weeks of consistency to see a difference)
Was she ever fully potty trained? i.e. was she fully potty trained and THEN started having accidents during the day? If not...she may not be aware of when she needs to go to the potty soon enough to make it. In that case, it is a developmental issue and no amount of reward and punishment is going to help until her body matures.
As for night time wetting I think it is pretty normal at this age. Even children who are fully potty trained during the day may wet the bed.
